Atenolol API (CAS 29122-68-7) is an Active Pharmaceutical Ingredient used in the formulation of prescription and/or over-the-counter pharmaceutical products. Swapnroop Drugs and Pharmaceuticals manufactures and supplies Atenolol API with pharmacopeial compliance (IP/BP/EP/USP as applicable) from our WHO-GMP certified facility in Aurangabad (MIDC Shendra), Maharashtra — one of India's premier pharmaceutical manufacturing zones with robust regulatory infrastructure.
Pharmaceutical formulation companies sourcing Atenolol API require consistent polymorphic or salt form characterisation, batch-to-batch HPLC purity ≥98% (or per specific pharmacopeial monograph), validated residual solvent control per ICH Q3C, and full impurity profiling against pharmacopeial limits. Our quality control laboratory performs complete pharmacopeial testing with USP/EP/IP validated analytical methods before every batch release.
Swapnroop's Atenolol API supply is backed by WHO-GMP certified manufacturing, a qualified vendor documentation package (CoA, MSDS, Certificate of Origin, stability data), and dedicated technical support for domestic formulation companies and international export customers. We maintain inventory for rapid order fulfilment across 25+ countries served from our Aurangabad facility.
Atenolol API is supplied in double-polyethylene-lined HDPE drums or fiber drums (25 kg net) with desiccant and nitrogen head-space. Smaller quantities (1 kg, 5 kg) in sealed HDPE jars for R&D programs. All packaging labelled with batch, grade, and pharmacopeial standard.
Get Bulk QuoteThe CAS number for Atenolol is 29122-68-7. It is a cardioselective beta-1 adrenergic blocker widely used for hypertension, angina, and arrhythmia management.
Atenolol preferentially binds beta-1 adrenergic receptors in the heart over beta-2 receptors in bronchial and vascular smooth muscle. This cardioselectivity reduces risk of bronchospasm compared to non-selective beta-blockers, making it safer for patients with mild respiratory conditions.
Per BP/USP specifications, key impurities include Atenolol Impurity A (4-(2-hydroxyethyl)phenol, limit ≤0.1%) and Impurity B (atenolol related compound). Full impurity certificate is provided with every commercial batch.
MOQ is 25 kg with competitive pricing for larger volumes (100 kg, 500 kg) serving India's high-volume antihypertensive tablet manufacturing sector.
