Precision Chemistry. Structured Global Supply.
Product Center
Palica Chem supplies selected industrial and specialty chemicals through a specification-driven workflow covering grade definition, analytical documentation, impurity review, packaging compatibility, and export execution. From technical requirement to commercial delivery, we align product quality, documentation, and logistics for reliable international supply.
Gas Odorants
Odorants for natural gas distribution networks and for biomethane injection into the grid. Dangerous goods classification, UN-certified packaging and DG declaration are prepared in-house — for this line the export documentation is as much of the job as the material.
- Tetrahydrothiophene (THT) — CAS 110-01-0 — the reference odorant across European gas networks, supplied in drums and ISO tanks
- Ethyl Mercaptan (Ethanethiol) — CAS 75-08-1 — used alone or in odorant blends
Biomethane and RNG projects are supplied on the same terms as conventional gas distribution.
Oilfield & Acidizing Chemicals
Film-forming corrosion inhibitors for well acidizing and acid cleaning, and the raw materials formulators build their own inhibitor packages from. Quoted against the acid system and the metallurgy, not against a catalogue number.
- Acidizing Corrosion Inhibitor — quinoline quaternary ammonium film-former for HCl, HCl/HF and selected organic acids; 250-320°F service, stated to 350°F (177°C) depending on the acid blend
- Quaternary ammonium compounds and imidazoline derivatives, including thiourea- and phosphorus-modified grades — raw materials, supplied to specification
The line is described on the Corrosion Inhibitors page.
Reactive Mesogens & Liquid Crystal Monomers
Diacrylate and monoacrylate reactive mesogens for liquid crystal elastomers, 4D printing, soft robotics and photoswitches. Research to pilot quantities; small-batch orders are routine for this line.
- RM257 — CAS 174063-87-7 — mesogenic diacrylate and liquid crystal monomer for polymer-network and UV-curable formulations
- RM82 — CAS 125248-71-7 — diacrylate reactive mesogen for LCE inks, 4D-printed actuators and liquid crystalline vitrimers
- Monofunctional reactive mesogens for network tuning — enquire for current range
Peptide Synthesis Reagents
Reagents for peptide coupling, Fmoc deprotection and protecting-group chemistry.
- T4P — n-Butylphosphonic Anhydride, CAS 163755-62-2 — 50% solution in ethyl acetate, THF, DCM or diethyl carbonate
- 4-Methylpiperidine — CAS 626-58-4 — evaluated as a base and as an alternative to piperidine for Fmoc deprotection
- Trityl Chloride — CAS 76-83-5 — reagent for introducing trityl protecting groups
The three products are described on the Peptide Synthesis Reagents page.
N-Heterocyclic Building Blocks
Pyridine and lactam products for API synthesis, process chemistry and formulation work.
- 2-Pyrrolidone (2-P) — CAS 616-45-5 — polar solvent for extraction, coatings and polymer production
- 3-Hydroxypyridine — CAS 109-00-2
- Picolinic acid — CAS 98-98-6
- Ethyl Nicotinate — CAS 614-18-6
- 2-Aminopyridine — CAS 504-29-0
- 2-Methylquinoline (Quinaldine) — CAS 91-63-4 — available in 87% and 99% grades for organic synthesis, dyes and other quinoline derivatives
Surfactants & Biosurfactants
- Rhamnolipid Biosurfactant — fermentation-derived glycolipid biosurfactant for cleaning, personal-care and agrochemical formulation development; the grade is defined by congener profile and active-content basis rather than by one registry number
- Linear Alkylbenzene Sulphonic Acid (LABSA) — CAS 27176-87-0 — detergent and cleaning-formulation intermediate
Biocidal & Repellent Actives
Actives supplied to formulators whose finished product is registered — a repellent, a preservative, a wood or coating fungicide. On this line the purchase specification sits downstream of the buyer's own authorisation, so the named impurity limits and the lot certificate of analysis carry more weight than the headline assay.
- DEET — N,N-Diethyl-m-toluamide, CAS 134-62-3 — the repellent active; 99.00% min. by GC area with N,N-diethylbenzamide held to 0.30% max., in 200 kg HDPE drums. Not regulated under ADR/RID, IMDG or IATA
- 8-Hydroxyquinoline — CAS 148-24-3 — chelating biocide and intermediate
- 8-Hydroxyquinoline Sulfate — CAS 134-31-6 — the water-soluble sulfate salt
- Copper 8-Hydroxyquinoline (Oxine-Copper) — CAS 10380-28-6 — copper chelate used as a fungicide and mildew-proofing agent for textiles, paints, paper and wood
The derivatives are described on the 8-Hydroxyquinoline Derivatives page; what a DEET specification's impurity limit says about the route the material was made by is set out in a separate note.
Specialty Solvents & Heavy Liquids
High-density liquids and specialty solvents for mineral separation, formulation and synthesis.
- Tetrabromoethane (TBE) — CAS 79-27-6 — high-density liquid for mineral separation in geological and mining laboratories
- Diiodomethane (Methylene Iodide) — CAS 75-11-6 — purity ≥99.50%; a high-density liquid used in laboratory mineral separation
Laboratory Sample Preparation
Standard and custom lithium borate fusion fluxes for laboratory sample preparation, with crucibles and cupels for fire assay workflows.
Every product with a page on this site is listed by registry number in the Product Index by CAS Number. Other products previously supplied remain available — contact us with a CAS number.
