1. Acts T-butyl-3-oxocyclobutanecarboxylate as a core cyclic ketone ester intermediate, efficiently synthesizing pharmaceutical raw materials for anti-inflammatory and cardiovascular drug R&D with high structural specificity.

2. Serves T-butyl-3-oxocyclobutanecarboxylate CAS 145549-76-4 as a key cyclobutane building block, stably preparing functional cyclic derivatives for agrochemical intermediate and fine chemical production with high reaction selectivity.

3. Functions as a fine chemical raw material, reliably fabricating specialty polymers with rigid 3-oxocyclobutyl structure for advanced coating and adhesive applications.

Store T-butyl-3-oxocyclobutanecarboxylate CAS 145549-76-4 at 5–25℃ in sealed amber glass/HDPE drums in a cool, dry, well-ventilated area, away from open fire, strong oxidants and strong acids. Wear nitrile gloves, safety goggles and organic vapor mask; avoid vapor inhalation, skin/eye contact and ingestion to prevent mild irritation. Reseal tightly post-use; keep away from excessive moisture; dispose of waste via licensed hazardous waste channels, prohibit direct water discharge, comply with cyclic ketone ester environmental regulations.

T-butyl-3-oxocyclobutanecarboxylate CAS 145549-76-4 is a low-toxic cyclic ester (oral LD50>3000mg/kg) with mild irritation only on prolonged contact, excellent stability under normal storage without hydrolysis/decomposition. T-butyl-3-oxocyclobutanecarboxylate features high ester group reactivity for hydrolysis/ester exchange, good solubility in common organic solvents, the 3-oxocyclobutyl core enhances molecular rigidity, ensuring high synthesis yield and product purity for pharmaceutical & fine chemical production.
