Chemical Structure

Pirimicarb-desamido-desmethyl CAS 78195-30-9 chemical structure

Description

Pirimicarb-desamido-desmethyl (CAS 78195-30-9) is a high-purity analytical reference standard with the molecular formula C7H11N3O and a molecular weight of 153.18 g/mol.

Owing to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system, Pirimicarb-desamido-desmethyl is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 153.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
