Description
2,5-DICHLOROBENZOIC ACID METHYL ESTER 2905-69-3 AS02940 LABOTEST-BB LT00847973 LABOTEST-BB LT03331250 LABOTEST-BB LT03381168 Methyl 2,5-dichlorobenzoate RARECHEM AL BF 0427 (CAS 2905-69-3) is a high-purity analytical reference standard with the molecular formula C8H12Cl2O2 and a molecular weight of 211.09 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 2,5-DICHLOROBENZOIC ACID METHYL ESTER 2905-69-3 AS02940 LABOTEST-BB LT00847973 LABOTEST-BB LT03331250 LABOTEST-BB LT03381168 Methyl 2,5-dichlorobenzoate RARECHEM AL BF 0427 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 211.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
