  • First-aid measures: General adviceConsult a physician. Show this safety data sheet to the doctor in attendance.If inhaled If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician. In case of skin contact Wash off with soap and plenty of water. Consult a physician. In case of eye contact Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician. If swallowed Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.

  • Fire-fighting measures: Suitable extinguishing media Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Wear self-contained breathing apparatus for firefighting if necessary.

  • Accidental release measures: Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8. Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided. Pick up and arrange disposal. Sweep up and shovel. Keep in suitable, closed containers for disposal.

  • Handling and storage: Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2. Store in cool place. Keep container tightly closed in a dry and well-ventilated place.

  • Exposure controls/personal protection:Occupational Exposure limit valuesBiological limit values Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday. Eye/face protection Safety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU). Skin protection Wear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.

Compounds Related to Acyclovir. IX. Synthesis of 7-Hydroxy-2,5-Dioxaheptyl Derivatives of Nucleic Bases

Smirnov, I. P.,Tsilevich, T. L.,Kochetkova, S. V.,Gottikh, B. P.,Shchaveleva, I. L.,Florent'ev, V. L.

7-Hydroxy-2,5-dioxaheptyl and racemic 7-hydroxy-1-methyl-2,5-dioxaheptyl derivatives of uracil, thymine, cytosine, adenine, guanine, and 1,2,4-triazole-3-carboxamide were synthesized using 7-acetyloxy-1-chlor-2,5-dioxaheptane and 8-acetyloxy-2-chlor-3,6-d

Crown Ether Acetals: Synthesis and Characterisation of a Family of Novel Oxygen Macrocyclic Compounds

Gold, Victor,,Sghibartz, Cristian M.

, p. 453 - 458 (2007/10/02)

The synthesis of cyclic acetals containing a repetitive -CH2CH2O- grouping within the ring is described.Compounds with rings of up to thirty-four members and with one or two acetal groups have been prepared and characterised by their 1H and 13C n.m.r. spectra, the amount of acetaldehyde released on hydrolysis, and their molecular weights.The general formulae of the new compounds are CH3CH(OCH2CH2)nO with n = 2-6; CH3CH(OCH2CH2)nOCH(CH3)(OCH2CH2)nO, with n = 2-5; RCH(OCH2CH2)2O with R = Pr, Pri, Ph; and C6H4O(CH2CH2O)nCH(CH3)(OCH2CH2)nO, with n = 0, 1, 2.As precursors for compounds related to the last of these series, the new open-chain dichloroacetals CH3CH2, with n = 2, 3 were prepared.Rate constants for the acid catalysed hydrolysis of some of the new acetals are reported.
