Benzoic acid, 2-hydroxy-, anhydride, also known as 2-hydroxybenzoic anhydride or salicylic anhydride, is a chemical compound with the molecular formula C14H10O3. It is a white crystalline solid that is derived from the dehydration of 2-hydroxybenzoic acid, also known as salicylic acid. This anhydride is an important intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds. It is used in the production of aspirin, a widely used pain reliever and anti-inflammatory drug, as well as in the synthesis of other salicylate derivatives. Salicylic anhydride is also employed in the manufacturing of dyes, resins, and other specialty chemicals. Due to its reactivity, it is essential to handle Benzoic acid, 2-hydroxy-, anhydride with care, as it can be harmful if inhaled, ingested, or absorbed through the skin.

607-87-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 607-87-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,0 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 607-87:
(5*6)+(4*0)+(3*7)+(2*8)+(1*7)=74
74 % 10 = 4
So 607-87-4 is a valid CAS Registry Number.

Acid anhydrides and the unexpected N,N-diethylamides derived from the reaction of carboxylic acids with Ph3P/I2/Et3N

Phakhodee, Wong,Duangkamol, Chuthamat,Wangngae, Sirilak,Pattarawarapan, Mookda

, p. 325 - 328 (2016)

The formation of acid anhydrides from the phosphorous-mediated activation of carboxylic acids was investigated. Under various systems, activation of benzoic acid in the presence of base led to the formation of benzoic anhydride at different rates depending on the reactivity of the reagents. Using the Ph3P-I2/Et3N combination, most aryl acids were converted into the corresponding anhydrides in high yields within 5-10 min. However, for nitro-substituted derivatives, unexpectedly, N,N-diethylamides were isolated without anhydride formation. These results indicated the pronounced effect of substituents in governing these potential side reactions which can significantly affect the yields of acylation reactions promoted by phosphonium species.
