Chemical Structure

Ethyl 2-chloro-7,8-dihydro-5H-pyrano[4,3-d]pyrimidine-4-carboxylate CAS 1260666-06-5 chemical structure

Description

As a certified reference material (CRM), Ethyl 2-chloro-7,8-dihydro-5H-pyrano[4,3-d]pyrimidine-4-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

CATO supplies Ethyl 2-chloro-7,8-dihydro-5H-pyrano[4,3-d]pyrimidine-4-carboxylate (CAS 1260666-06-5), a certified reference material (molecular formula C10H11ClN2O3, MW 242.66 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Ethyl 2-chloro-7,8-dihydro-5H-pyrano[4,3-d]pyrimidine-4-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 242.66 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.
