Specialty aroma chemistry lives or dies in the detail — and at Chemshel, that detail is in the hands of our laboratory team in Purulia. Every batch of Ambrettolide that leaves our facility has passed through analysts who treat Gas Chromatography (GC) traces the way a jeweller treats a stone: nothing ships until it meets the standard.
Our technicians run raw-material screenings before production begins, monitor the synthetic process at every stage, and verify each finished lot against stringent physical-chemical and olfactive specifications.
Rigorous operational checkpoints from natural input sorting to final drum sealing in Purulia, West Bengal.
Incoming chemical assay and screening on natural bio-resin feedstocks (raw sticklac and reagents) before entering the synthesis reactors.
Technicians monitor reaction parameters, intermediate pH values, thermal curves, and conversion stoichiometry during aleuritic acid extraction and cyclization.
High-resolution GC-FID chromatography verifies the ≥ 98.0% minimum purity threshold, isomer distributions, and total absence of undesirable volatiles.
Complete lot archival, individual Certificate of Analysis (CoA) release, and drum-level barcode tracking for export to global fragrance houses.
