6-chloro-5-fluoro-pyridine-3-carbaldehyde CAS 950691-52-8 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

6-chloro-5-fluoro-pyridine-3-carbaldehyde (CAS 950691-52-8), molecular formula C6H9ClFNO and molecular weight 165.59 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 6-chloro-5-fluoro-pyridine-3-carbaldehyde (C6H9ClFNO) contains an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 165.59 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
