133186-55-7 Usage

Preparation

Preparation by Fries rearrangement of 2,6-difluorophenyl acetate (b.p.7 62–63°) with aluminium chloride at 140–150° for 5 h under nitrogen atmosphere (56%).

Check Digit Verification of cas no

The CAS Registry Mumber 133186-55-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,1,8 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 133186-55:
(8*1)+(7*3)+(6*3)+(5*1)+(4*8)+(3*6)+(2*5)+(1*5)=117
117 % 10 = 7
So 133186-55-7 is a valid CAS Registry Number.

Synthesis of pentafluorobenzyloxy mono- to tetrafluoroacetophenones

Xu, Linxiao,Giese, Roger W.

, p. 47 - 52 (1994)

Pentafluorobenzyloxyacetophenones are formed by reacting 2',3',4',5',6'-pentafluoroacetophenone and 2',3',4',5'-tetrafluoroacetophenone with pentafluorobenzyl alcohol (PFBA) in refluxing toluene under phase-transfer conditions.This provided seven new such

Development of pH-activatable fluorescent probes for rapid visualization of metastatic tumours and fluorescence-guided surgeryviatopical spraying

Cao, Wenwen,Li, Xiaoxin,Wu, Peng,Xiong, Hu

supporting information, p. 10636 - 10639 (2021/10/19)

A series of pH-activatable aza-BODIPY-based fluorescent probes were developed for rapid cancer visualization and real-time fluorescence-guided surgery by harnessing topical spraying. These probes exhibited good water-solubility, a tunable pKafrom 5.0 to 7.9, and stable intense NIR emission at ~725 nm under acidic conditions.AzaB5with a pKavalue of 6.7 was able to rapidly and clearly visualize pulmonary and abdominal metastatic tumours including tiny metastases less than 2 mmviatopical spraying, further improving intraoperative fluorescence-guided resection. We believe thatAzaB5is promising as a powerful tool to rapidly delineate a broad range of malignancies and assist surgical tumour resection.
