COLABA OUD · B2B COMMERCE & REGULATORY COMPLIANCE
GC-MS Testing & Laboratory Purity Standards for Dehn Al Oud: Sesquiterpenes, Adulteration & Chemical Fingerprinting | Colaba Oud
Gas chromatography-mass spectrometry (GC-MS) provides definitive scientific proof of agarwood oil purity. Authentic Dehn Al Oud displays distinctive sesquiterpene hydrocarbon and oxygenated sesquiterpene profiles, including agarospirol, jinkoh-eremol, and valencene, while immediately exposing adulterants such as dioctyl phthalate, paraffin, and synthetic aroma compounds.

The Chemistry of Pure Dehn Al Oud: Critical Biomarkers
True hydro-distilled agarwood oil consists of over 150 complex sesquiterpenoids and chromone derivatives. In genuine Indian Assam oud, high concentrations of agarospirol and alpha-agarofuran create deep woody, balsamic, and animalic facets. In Cambodian oils, jinkoh-eremol and hydroxy-dihydroagarofuran generate luscious dried-fruit and honeyed sweetness.
Common Market Adulterants Detected by Mass Spectrometry
Market adulteration ranges from diluents like odorless dipropylene glycol (DPG) and mineral paraffin oils to dangerous chemical fixatives like dioctyl phthalate (DOP). Synthetic single molecules (such as synthetic oud bases) mimic initial top notes but reveal flat, unreactive peaks on mass chromatograms.
The Colaba Oud Quality Seal: Spectral Fingerprinting for Every Batch
Every distillation batch at Colaba Oud undergoes mandatory third-party GC-MS spectral screening before bottling. We publish spectral breakdown metrics for wholesale accounts and bespoke perfumery clients, ensuring institutional trust and uncompromising purity.
